Step 13: Light up Your Bike

Because simply having a bamboo bicycle is not unusual enough, you may want to add some lights to it to garner even more attention.  I built these simple wheel lights for the Halloween Critical Mass ride in Atlanta.  

The spoke lights are based off a very simple circuit.  Each one is composed of ten sets of four LED's and a resistor in a series, in parallel.  I chose to use 3mm orange LED's because they were for Halloween.
